摘要
高强浮力材料对提高潜器的有效载荷,减小其外形尺寸,提高其水下安全运动性能具有重要作用.以环氧树脂为基体材料,通过填充大量空心玻璃微珠研制出密度低、强度高的固体浮力材料.对选用的WSR6101环氧树脂基体材料,筛选出适宜固化剂为顺丁烯二酸酐(MPD)、4,4’-二氨基二苯砜(DDS).通过对空心玻璃微珠进行表面改性处理,提高其和聚合物的相溶性,使玻璃微珠掺加量大幅度提高,最高可达20%.通过优化试验,获得了密度0.61—0.75g/cm^3,压缩强度40-68.96MPa,且吸水率很低的深海高强浮力材料,性能优于国产同类材料,达到国际先进水平.对浮力材料的屈服破坏进行微观机理分析,指出应选用粘结力强的基体材料和壁厚的空心玻璃微珠.
The buoyancy material plays an important role in deep sea hidden machine to provide enough buoyancy, to increase its efficient loading, reduce its dimensions, and improve its submarine safe movement capability. The low density as well as high intensity material was made by filling great amount of hollow micro - glass ball in base material epoxy resin. The m-pheny lenediamine (MPD) or 4,4' -diaminodiphenylsulfone - (DDS) were chosen as the best solidifying reagent. With modifying the surface of hollow glass ball, the mixing degree between polymer and hollow glass ball increased as well as mixing quantity of hollow glass ball. Through the systematic optimization on all the facts affecting the treatment the deep sea buoyancy material with low absorption was got, its density was 0. 61 - 0. 75 g/cm^3, its compression strength was 40 - 68.96 MPa. The microcosmic destruction mechanism of buoyancy material was discussed.
